attorney I Patented Apr. 13, 1937 UNITED STATES PATENT OFFICE 2,076,689snorrmc BAG Hal-ford K. Steen, Newburgh, N. Y. Application July 27,1935, Serial No. 33,553 4 Claims. (01; eas -s4) This invention relatesto .shopping bags made of paper or other suitable material and to themethod employed in their manufacture, and constitutes an improvementover that described and claimed in United States. Patent No. 1,799,072which was issued to me on March 31, 1931, for -a Method of manufacturingshopping bags.

In the above referred to patent, the cord handles were secured to theinside of the bag by 10 an adhesive and a reinforcing strip thatextended the entire length of the bag web, from which the tube and bagwere formed, and to provide for the extension or projection of theproper portion of the handles to form a grip beyond the upper 15 or openend of the finished bag, the end v of the bag was cut or slotted downfor a portion of the length of the handle and was then folded over alonga crease which was formed in the making so that this fold could beeither pasted to the inside of the bag or left loose to form a flapwhich could be folded to partly close the bag.

But it has been found that this method of manufacture not only consumestime and uses a greater amount of both the bag stock and the reinforcingmaterial than is necessary, but does not provide such a pleasingappearance or as serviceable a bag as one where the handle projects froman even single thickness of bag material. i 30 To facilitate thebundling or packing of the folded bags in bales for shipment and toprevent the stacked handles from building up in thickness thus takingtoo much room in the bale, and to give a closer formation adding greatlyin the 35 manufacture, especially when a bottomer is used as the stacksof bags in the machine do not have to be replenished so often, I havenested the handles. 7

Also by the nesting of the handles, parts of the 40 machine through orover which the. attached handles have to pass, do not have to berelieved so much thus eliminating the possibility to creep and themachine will thus operate to better advantage. 45 While I have shown anddescribed these handles as being attached to the bag by gummed patches,it is to be understood that they may be attached by other suitablemeans, such as staples or tied through holes formed inthe web:

50 For this purpose I have added to my above mentioned patent the ideaof locating the attached handles to the web in such positions that whenthe bags are folded, the handles will be nested one within the other sothat they will lie 55 side by side and only occupy the thickness of onesingle handle in the stacking of the bags,' thus saving over 40 percentof the storage and shipping space required for the same number ofbags that were made in the old manner. 50 Another object of theinvention is to, provide a bag iirwhich the cord handles are secured tothe interior thereof by an adhesiv)eapplied to predeterminedlocalsurfaceson the web and adapted to receive patches which have receivedthe handles and which are both secured to the web by the adhesive orother suitable means, to form a firm and strong junction.

Another object of the invention is to provide a bag in which the cordhandles extend beyond the open end of the bag without having to have'the end of the bag folded over or formed with a flap.

Another object of the invention 1S5t0 provide a bag in which the cordhandles are so located and' attached that when the bag is folded, thehandles will nest one within the other to present a single thickness ofhandle and prevent building up when baled.

With these and other objects in view, my invention consists in certainnovel construction and combination of parts as will hereinafter be fullydescribed in the following descriptionand illustrated inthe accompanyingdrawings which form a part hereof and in which like figures of referencerefer to corresponding parts in all of the views, and it. is understoodthat slight changes may be made without departing from the spirit of theinvention.

In carrying out my invention the mechanism required for the varioussteps and operations may 20, and these patches are carried past the pads28" be constructed in a single machine, or as a part of a bag makingmachine of the usual type, or the bags may be taken from my apparatuswhen in the form of a tube and bottomed and folded in another machine ifdesired, and in the description and illustrations of this presentinvention I have embodied my invention in a bag making machine withoutthe bottoming and folding means.

Referring to the drawings:

I have taken the usual bag making machine A travel through the machineis indicated by the broken lines.

From the stock roll ill the web travels past the seam pasting rolls I!where paste is applied to one edge I! to later on hold the web in theform of a tube, and the web next travels past the knife l6 where the twoaligned slits 24, which locate the position of the handles iii are made,and if it is desired to form the bag with a flap 11, a crease 26 is nowplaced in the web by the creaser 25, and from either the slitting knivesH5 or the creaser 25 the web is carried past the adhesive pads it whichtransfer adhesive from the pot H to predetermined local surfaces 16 onthe web adjacent to the slits 2| for the reception of the handles i8 andpatches i9.

While this is taking place, a pair of cord handles i8 and theirattaching patches N are being prepared as follows: A'piece of cord 23 isdrawn from the stock roll 21; cut off and formed into the D-shapedhandles il.. From the roll of strip,

stock, either plain or gummed, a strip 2i isfed and from this are cutthe patches I! by the knife on the roller 32, which either appliesmoisture or gum to the patches in two parallel stripes 29 T on theirsurface. 7 7

The transfer roller ll that carries these patches I9 and transfers themto the web II, is provided with the pins II which perforate the patchlfl and carry it along as well as the formedhandles ill upon the patchesin the moist contact with the pins 3|.

As the traveling web it reaches the proper gum and in station inthe'machine the transfer roller 30 places the gummed patches i9 and thehandles it upon the previously gummed local surfaces It on the web,which is then carried throughthe press rollers 22 that press the patchesl9 and handles i8 upon the web Ii to form a firm and strong junction. I

From the handle pressing roller 22, the web ii is carried to the usualtube forming device 34 which brings together the edges of the web Iiwhich are retained by the paste seam I5.

After the bag tube has been formed, it is severed from the web Ii by thecut-off knife 26 which makes a transverse cut I! in aligned relationwith the slits 24 if the bag is to be made without a flap ll.

But should it be desiredito form the bag with the flap l1, then when theoriginal slits 2| are made, additional slits are made at right anglesthereto in line with the body of the handles l8, or these longitudinalslits may be made without the transverse slits; the web Ii creases atthe proper location to form the flap II, the crease 26 acting as a guidein folding the flap II.

The bag tube is now taken to the bottoming device where the bottom isformed, and the bag isfthen folded and baled.

The paste or adhesive rolls l2, l3, and 20 are of the usual type havingraised pads l3 and 28 for transferring the paste. from the pot to theweb ii, and are provided with the cut-out portions 35.

To provide for the folded bag not building up in thickness in the baledue to the handles i8 stacking one upon the other, I have formed the twohandles of slightly different dimensions, and

- have located them both upon the patches and terposed between thepatches and the inner surface of the body portion'with their grippingportions projecting from the open end of thebas, and nesting one withinother when the bag is folded.

2. As an article: of manufacture, a shopping bag comprising a bodyportion having an open end and a closed. end and adapted to be folded{when not in use, patches of reinforcing material secured to the innersurface of said bag body adjacent to the open end, handles of differentwidth interposed between said patches and the bag and secured theretowith their grip portions extending from the open end of the bag andadapted to nest with each other to form a single thickness of handlewhen the bag is in a folded state. 3. As an article {of manufacture, ahandled shoppingbag' comprising a body having an' open end and a closedend and adapted to be folded flat forming two sides, patches secured tosaidsides adjacent the open end, handles formed with grips and differentwidth body portions, said body portions of the handles interposedbetween the patches and the-bag and secured to both with the gripportions "extending from the open end of the bag, and nesting one withinthe other when the bag is folded.
